\section{Data Collection}

\setlength{\parskip}{1.0\baselineskip}
\par For this project, the social platform we chose was \textbf{arXiv}. The goal is to build a co-authorship network based on collaborations between papers and authors.

\par The \href{https://arxiv.org/help/api}{arXiv API} allows users to programmatically access millions of electronic papers hosted on arXiv.org. The arXiv API user manual provides the basic syntax for paper retrieval. According to the syntax provided, the metadata of the corresponding paper, that is, the metadata, includes information such as the paper title, author, abstract, and comment.

\par According to the access method provided by the arXiv API, we crawl the information of 100 related papers according to the keywords and arXiv API returns data in xml format. Through analysis and statistics, we can know that the data contains 249 different authors and 455 pairs of authors who have cooperated with each other.
